Answer:
vertex = (5, - 1 )
Step-by-step explanation:
The focus and directrix are equidistant from the vertex
Since the equation of directrix is y = - 3 then the parabola is vertical,
The distance between the focus and directrix is
| 1 - (- 3) | = | 4 | = 2
Thus the vertex is 2 units below the focus
vertex = (5, 1 - 2 ) = (5, - 1 )
A parabola has focus (5, 1) then the vertex of the parabola will be (5, -1).
What is a Parabola?A location on the curve that is equally spaced from both a fixed location and a fixed line is referred to as a parabola. The parabola's focus requires and fixed line are referred to as its foci and directrix, respectively.
As per the given information in the question,
The focus and directrix are equidistant from the vertex then,
The parabola is vertical because the directrix's equation is y = - 3; hence, the focus and directrix are separated by:
|1 - (-3)| = |4| = 2
The vertex is therefore 2 units below the focus.
vertex = (5, 1 - 2) = (5, -1)

Hamish buvs a new car for $20000
The car depreciates in value by 19% each year.
Work out the value of the car at the end of 3 years.
Give your answer to the nearest $
Answer:
The correct answer is $10,629
Step-by-step explanation:
Here is how I got it!
First, you will have to borrow the 20,000 from the word problem.
Next, multiply 20,000 with 0.81 with the power of 3
[tex]20,000*0.81^3=n[/tex]
The 3 is the number of years, n is the nearest $ answer.
--
First, do [tex]0.81^3[/tex]
[tex]0.81*0.81*0.81=0.531441[/tex]
(Wow, that's a crazy number!)
--
With 0.531441, multiply it with 20,000
[tex]20,000*0.531441=10628.82[/tex]
10,628.82 is technically (in money) $10,628.82 (with .82 being eighty-two cents).
--
Finally, it states to answer to the nearest $.
Just round up the .82 to 1 dollar which will just add one more dollar to 10,628
[tex]10,628[/tex] ⇒ [tex]10,629[/tex]
Add you $ symbol
With the result being: $10,629
Answer:
$10629
Step-by-step explanation:
First you have to work otu the percentage decrease:
100 - 19 = 81
81/100 = 0.81 (/ means divide)
Then you have to work the amount after 3 years:
Long Method
20000 x 0.81 = 16200
16200 x 0.81 = 13122
13122 x 0.81 = 10628.82
or Short Method
20000 x 0.81³ = 10628.82
Finally you round it to the nearest $:
10628.82 ⇒ 10629

Alice earns $185 for working 14.8 hours each week. How much money will Alice earn if she increased her hours to 18 1/2 hours per week?
:)
Step-by-step explanation:
185 is to 14.8 as x is to 18.5
185/14.8 = x/18.5
x = 185(18.5)/14.8
x = $231.25

In the triangle, m∠JKL = 3° and m∠KJL = 17°. Find m∠JLM.
Answer:
160
Step-by-step explanation:
the middle letters ttell you which corner of the triangle has that degree.
all corners added together must equal 180 in a triangle
jkl has k in the middle so k is 3°
kjl has J in the middle so J is 17°
jlm has L in the middle and is unknown
K + J + L = 180
3+17+L = 180
20 + L = 180
L = 160
Answer:160 degrees
Step-by-step explanation:
180-3-17=160
All triangles neasure 180 degrees
